UNITED STATES EMANUEL ESOHELBAOHER, OF NEW YORK, N. Y.

SEWING-MACHINE ATTACHMENT.

Specification of Letters Patent.

Patented Oct. 1, 1907.

1 Application filed April 29, 1907- Serial No. 370,963.

To all whom it may concern:

Be it known that I, EMANUEL ESCHELBACHER, a citizen of the UnitedStates, residing in the city of New York, county and State of New York,have invented certain new and useful Improvements in Sewing-MachineAttachments, of which the following is a full, clear, and exactspecification.

This invention relates to sewing machine attachments.

The object of the invention is to provide a strong, simple, durable,inexpensive and thoroughly efficient attachment adapted to produceeither single or double plaits or tucks.

With the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of the following claims without departing from the spirit of theinvention.

In the accompanying drawing forming part of this specification, Figure 1is a front elevation of a plaiting attachment constructed in accordancewith the invention, a portion of the device being broken away. Fig. 2isa section on the line 2-2 of Fig. 1, with the needle bar andpresser-foot removed. Fig. 3 is a side elevation of the constructionshown in Fig. 1. Fig. 4 is a plan view of the presser-foot. Fig. 5 is aplan view showing a slightly modified arrangement of plate and guidemember. Fig. 6, is an end elevation of the construction shown in Fig. 5.Fig. 7, is a cross section through a piece of fabric formed with adouble plait by means of the attachment of the present invention. Fig.8, is a detail view of the plate and guide members shown in Fig. 1.

Like reference numerals indicate corresponding parts in the differentfigures of the drawing.

Referring to Fig. 1 of the drawings the reference numeral 1, indicates aplate which is suitably mounted in the sewing-machine-table above thebobbin-carriers. The plate 1, is preferably thickened as shown in Fig.8, so that it will extend at its upper end above the upper surface ofthe sewing-machine-table which is indicated by the horizontal lineextending across the lower end of Fig. 1. The plate 1 in the side edgesthereof above the sewing-machine-table is formed with a pair of grooves3, which are approximately U-shape in cross section and serve to producean upper guide member 4 and a lower guide member 5. As shown in the drawing, the pairs of upper and lower guide members 4 and 5 project inopposite directions. Extending into the space between each pair of upperand lower guide members 4 and 5 is a tongue 6, which, as shownparticularly in Fig. 2, preferably is of approximately semicrescentshape. The pointed forward ends 7 of the two tongues 6 preferably extendoutwardly in advance of the plate 1. As shown in Figs. 1 and 2, the twotongues 6 project in opposite directions, and the tongues and 'guidemembers 4 and 5 overlap each other as shown, so

that whena piece of fabric is fed in the usual direction, it passesunder the two tongues 6, around through the grooves 3 and over the topof the plate 1, so as to produce double plaits as shown clearly in Fig.7. The resser-foot and double needles hereinafter described, operate onthe fabric in rear of the plate 1 and tongues 6 so as to stitch theplaits as they leave the grooves 3 of the plate 1. i

For the purpose of permitting the tongues 6 to be adjusted a greater orlesser distance into the grooves 3, so as to regulate the width of theplaits, each of the tongues 6 is bent upward at an intermedinte portionthereof as indicated at 10, and is provided with an extension 11 inwhich is formed a longitudinal slot as indicated at 12 in Fig. 2. Theslotted extension 11 of each tongue 6 rests upon the horizontal portion14 of what I shall-term a bracket A and is adjustably secured thereto bymeans such as the screws 15. By loosening the screws 15, the tongue 6can be adjusted toward or from the plate 1. Integrally connected withthe one edge of the horizontal portion 14 of each bracket A is avertical extension 16 which is formed with a longitudinal slot 17, andis adjustably connected with an angular member 18 by means such as thescrews 19. By loosening the screws 19, each bracket can be verticallyadjusted upon the member 18 so as to cause the tongue 6 to projectaccurately into the center of the grooves 3 in the plate 1. Each of theangular members 18 is pivotally connected as indicated at 20 with asupport 21, which, in the embodiment of the invention illustrated,consists of a portion of the ordinary sewing machine. When the twopivotal members 18 are raised as indicated by the dotted lines in Fig.1, the fabric to be plaited or tucked can be placed over the plate 1,after which when the pivotal members 18 are moved down into the fulllineposition shown in Fig. 1, the plaits will be formed as previouslydescribed. For the purpose of limiting the downward movement of the twopivotal members 18, limiting pins 22, are screwed into the support 21 asshown in Figs. 1 and 3. In order to permit the parts of the attachmentto be locked in the positions shown in Fig. 1, locking devices such as25 are employed. Each of the locking devices 25 preferably is formedwith an integral vertically extending ear 26 which is pivotally'mountedat 27 upon the piv otal member 18. Each of the locking devices 25 isalso provided with an upwardly bent end 28 which is adapted to fit intoa suitable groove or socket 29 formed in the support 21. A spring suchas 30 is employed for holding each locking device in operative position.When the end of the locking device is pressed upwardly, the pivotalmember 18 together with the tongues 6, can

be raised. The upward movement of the pivotal mem ber 18 is limited bythe bent end 28 of the locking device engaging a shoulder 32 upon thesupport 21.

The presser-foot is indicated by the reference numeral 35 in Figs. 1 and3, and is adjustably connected by means of screw 36 with a rod 37 whichdepends upon the support or head 21. The reference numeral 10 indicatesthe needle bar which is provided at its lower end with a head 41carrying a pair of needles 42 which work through perforations 43 formedin the prcsser-foot 35 as shown in Fig. 4 in the usual manner.

In the modified construction illustrated in Figs. 5 and 6, the upper andlower guide members l and 5 which form between them, the grooves 3 areadjustably mounted upon the plate 1. These guide members 4 and 5 areprovided with overlapping extensions 50, each of which extensions isiormed with a pair oi slots 51 through which extend screws 52 connectedwith the plate 1 By loosening the screws 52, the extensions may beadjusted away from each other so as to increase the distance between thetwo plaits 55 shown in Fig. 7. The arrangement 01' the other parts ofthe attachment including the tongues 6, is the same in Figs. 5 and 6 asthat shown in Fig. 1.

It will be understood that it it be desired to produce only a singleplait, instead of double plaits shown in Fig. 7, one of the tongues 6will be removed or left out of operation.

The plaiting attachment of the present invention is strong, simple,durable and inexpensive in construction as well as thoroughly el'licientin operation.

What is claimed is:

1. A plaiting attachment including a support of a pair of oppositelyextending pivotal members on said support,

a bracket adjustably connected with each pivotal member, a tongueadjustablv connected with each bracket, the two tongues extending inopposite directions, and a plate having a pair 01' oppositely extendingguide members overlapping said tongue.
